I have spoken before about Rangers players having to have that big-game mentality, and question marks are starting to arise around Alfredo Morelos in that regard.

Despite an impressive goalscoring record, he has yet to find the net against Celtic and has passed up some gilt-edged opportunities.

You are obviously more nervous when you play in these big games, and when you saw how tight he was when he got into good positions against Celtic and passed up those great opportunities, then the obvious thing to surmise is that the whole occasion got to him.

I watched him closely though in the previous week’s game against Falkirk, and twice he was through in exactly the same scenario as the first chance he had against Celtic, and he couldn’t beat the keeper. He hit the first one against the goalie, and then the second time he tried to round him, and the keeper did well to get it at his feet.

So, he has a problem when he is running through at distance with just the keeper to beat, and I think that’s evident.

There’s no excuses about the one in the 88th minute. That will go down in history and no one will ever forget it, especially him. It was such a big game and what a chance to salvage something from it. I just don’t understand how he’s missed it.

His confidence must be shattered after that, and it’s important that he picks himself up quickly. He’s Rangers' top scorer, and the second-top scorer in the league.

I love his work-rate, and that is the edge he has on Jason Cummings. He will get in about centre-backs and make life difficult for them. Cummings is a more natural finisher though, there’s no doubt about that.

I just hope that the fact he has missed these chances against Celtic and has yet to score against them doesn’t become an albatross around his neck. He’s got to get back to scoring goals quickly on the domestic scene, and that starts on Saturday.
